1977年于东莞县东坑公社角社大队大片稻田在各代三化螟蛾盛发期,进行晶体管黑光灯回收标记三化螟蛾试验,探讨三化螟蛾趋光的规律和黑光灯对其的诱集效果。三化螟是当地水稻的主要害虫,每年发生五代,第三代多发,但全年以第二代为害双季连作早稻造成白穗的损失最大。 一、试验材料和方法 1.标记蛾来源及处理 (1)黑光灯诱集标记 在试区中心设置20瓦直流晶体管黑光灯1—3台(灯盆不加水),于晚上诱集田间螟蛾进行标记,当达到所需蛾量时,随即关灯,使标记蛾自行飞去,翌晨检查回收结果。每标记一个晚上,作标记一次计;如连续标记,则每晚更换标记颜色。
In 1977, dongguan commune, dongguan commune angle group brigade paddy fields in the generation of the mulberry moth Sheng period, the transistor black light lamp recycling mark moth moth test to investigate the light of the moth, moth and black light on its Trapping effect. Borer borer is the main pest of local rice, occurring five generations each year, the third generation of multiple, but throughout the year to the second generation of pests caused by double crop continuous rice for the largest loss of white spike. First, the test materials and methods 1. Marked moth sources and treatment (1) black light trap traps set in the center of the test area 20 watts DC lamp black light 1-3 units (no pot of water), in the evening trap field moth Marked, when the desired amount of moths is reached, the lights are turned off, causing the moths to fly on their own and the next morning to check the results. One night for each mark, make a mark once; as continuous mark, then change the mark color every night.
